I've seen a few weird ideas.. but this?? O_O
It surprises me that you haven't put any guns on it in order to blow the penguins to the next world.

Believe it or not, it's based on actual, real-world ships: the historical Japanese whale factories that, converted to tankers in WW2, drove American submariners nuts... ^_^

Armored CT's for a whaling ship? Whats the point?

In case the Whales start shooting at the ship. :-)

I wonder if it was to deflect heavy waves. Their are rough seas in whaling work....and sometimes competition that won't hesitate to shoot. Remember the old time raiders would target whaling fleets.

To provide some degree of protection against pirates until the cavalry can arrive...

Aside from the penguins...

Yes, quite lethal ordnance that. So... how many penguins are needed to sink that ship?
